Following the end of July announcement Hejnar Photo has released for sale a whole new series of Arca-Swiss® compatible quick release clamps.
The new Fnn clamp series design has aesthetic and functional improvements compared to the previous models as well as three unique prototype additions that cover a wider spectrum of uses.
The design is now distinctive making the clamps recognizable from other brands by the recesses in each side which serve both in lowering the clamp weigh and increasing its strength. Another improvement comes with the deeper relief grooves, that also have a new shape, which make the clamps compatible with most if not all the brands of rails with safety stop screws.

F50 Dual Side Quick Release Clamp
This a completely new excellent idea from Hejnar Photo for a clamp with two sided jaws.
The top side opens completely to put rail in while the bottom (reverse) side has two V cuts on the edges beside the smaller jaw, which require the clamp to be slid in and are there to prevent the bottom rail from falling off when the clamp is opened.
|F50 2.375" (6cm) long 0.825" (2cm) thick. The distance between its opposite surfaces is 0.45" (1,14cm). Weight 137gr.|
|F50 Bottom side showing the two V cuts beside he moving jaw and two relief grooves.|
|Best used as a sliding clamp for regulating position of two parallel dovetail equipped rails, e.g. a camera / lens plate on a longer rail.|
F68 Captive Quick Release Clamp
This is a world first from Chris Hejnar and Hejnar Photo!
A new idea for a self regulated clamp following the new F62 design but with one captive slot instead of center and side holes.
|The F68 is 2.375" (6cm) long with a short knob. One 3cm long captive slot which can take one or more 1/4"-20 captive screws. Weight 103gr.|
|F68A Bottom view of captive slot and two alignment pin holes.|
F69 Captive Quick Release Clamp
Another world first from Chris Hejnar and Hejnar Photo!
This idea was based on the Hejnar Photo F012 mini clamp in order to serve more as a support clamp. It has two captive slots instead of a center hole.
|The F69 is 1.5" (3,8cm) long with half short knob. Two 0.2" (5,08mm) long captive slots which can take one 1/4"-20 captive screw each replace the center hole. Weight 75gr.|
|F69 Bottom view of captive slots and a long alignment groove.|
